Description

Many riparian species have evolved adaptations to respond to rising water either through avoidance or submersion tolerance. We examined differences in submersion tolerance and burrowing behaviors among riparian and non-riparian populations of different wolf spider species. We also measured maximum burrow depth and escape behaviors of three species of burrowing wolf spider from riparian and non-riparian populations during a simulated flood event. Riparian wolf spiders had significantly shorter recovery times from submergence than non-riparian populations of the same species. We also found no significant differences across species in submergence tolerance. Of the three burrowing species, riparian spiders showed a marginally non-significant trend toward shorter escape times from burrows during simulated flooding and tended to have shallower burrows than the same species from non-riparian populations, however we found significant species differences in flood response that masked differences in riparian and non-riparian populations.
